Bills Rookie Keon Coleman Says He’s Learned ‘a Lot’ from Josh Allen: ‘Really Funny Dude’ (Exclusive)

Buffalo Bills rookie Keon Coleman says quarterback Josh Allen is teaching his teammates valuable lessons, on and off the football field.

Coleman, 21, tells PEOPLE exclusively that Allen, 28 — who led the Bills to a thrilling victory over Travis Kelce, Patrick Mahomes and the Kansas City Chiefs on Sunday, Nov. 17 — has taught him "a lot" since Coleman was drafted by Buffalo in April.

"Real funny dude," Coleman, a wide receiver, says of Allen, sharing that he's picked up "just, kind of, how everything works" and "how to go about your everyday business," from spending time with and observing Allen.

Still, Coleman says he can't reveal all of the knowledge Allen has bestowed upon him. "Some things need to go unsaid," says Coleman. "That's my guy though."

The Bills wide receiver — who scored two touchdowns for Buffalo so far this season — tells PEOPLE that his rookie season has been been "going pretty smooth" and life in the NFL is "pretty much living up to the expectations."

NFL rookies are traditionally given "rookie chores" by the team's veteran players and Coleman was no exception this season. He tells PEOPLE that his rookie duties included decorating a designated team room for Halloween.

"I don't even know what the stuff is called, but some little ornaments and stuff. I just put a little thing on the table, put some candles in there," says Coleman, who took a solo trip to the Dollar Tree to get the decor for his teammates.

One thing about life in the NFL that Coleman isn't a fan of, however, is the travel time.

"I hate the long flights," he says. "I don't get on them. I think the longest flight we've had is when we went to Seattle, but any longer than that, I'm not going...unless I absolutely have to go. But long flights, I can't do it."

Never having been out of the country, Coleman says he's "not that interested" in traveling far distances because of how much he resents long flights. "Maybe when I'm not playing an 18 game season, flying for seven months straight, then maybe I'll consider it. But nah, I'm not that interested."

Still, Coleman's job keeps him on the road, whether it's road games with the Bills or traveling for other work.

To combat his lack of patience for travel, Coleman has partnered with Booking.com to encourage Bills fans to make their trips easier this holiday season through the Genius Loyalty Program.

"It's a one-stop shop, gives you everything you need," says the wide receiver.

"Flights, hotels, rental cars, anything but ponchos," Coleman laughs, adding, "You'll be pretty good with everything else to get you nice discounts on everything."

If travel time weren't an issue, Coleman says he'd "make a few stops" around the world. "If the flight was 20 minutes, I'll go to Greece, I'll to Bali, I'll go see the Northern Lights."
